Swimming goggles

Abstract

Swimming goggles comprises a left frame and a right frame retaining lenses therein, a connecting apparatus connecting the lens frames, and straps movably received in outward sides of the lens frames. Engaging blocks are respectively formed on outward sides of the lens frame. Adjusting apparatuses are assembled to the engaging blocks for adjusting straps. Each adjusting apparatus includes a base and a cover assembled together, and a fixing axis assembled on the base. A biasing arm and a button are transversely extended from the fixing axis with opposite for biasing stop grooves of the strap. An arcuate spring extends outwardly from each engaging block to provide the button with return force. Normally the strap can move only in a single direction. When the button is pressed downwardly, the biasing arm moves upwardly to disengage from a stop groove, correspondingly the strap can move in two directions.

1. Swimming goggles comprising:
 a left frame and a right frame connected together by a connecting apparatus, the left and the right frames respectively having an outer surface and an inner surface, receiving passageways being defined between the outer surfaces and inner surfaces of the left and the right frames for accommodating lens, engaging blocks being respectively formed on outward sides of the left frame and the right frame, each engaging block having a first engaging portion and a second engaging portion, an arcuate spring extending outwardly from a side edge of each engaging block; and 
 at least an adjusting apparatus assembled to the engaging blocks, and each adjusting apparatus including: 
 a base having a first base wall and a second base wall opposing each other, an axis hole being defined respectively through the first base wall and the second base wall, a strap hole being defined between the first base wall and the second base wall and adjacent the axis hole for movably receiving a strap, en embedding portion being formed on the base for engaging with the first engaging portion of the engaging block; 
 a fixing axis pivotably received in the axis hole, a biasing arm transversely extending from the fixing axis for biasing stop grooves of the strip, and a button transversely extending from the fixing axis and assembled to the biasing arm for manual operation; and 
 a cover assembled with the base, and defining a through hole for receiving the button and forming a plurality of barbs thereon for locking the second engaging portion of the engaging block. 
 
   
   
     2. The swimming goggles as claimed in  claim 1 , wherein height of the engaging blocks are smaller than height of the left frame and the right frame, and the at least one adjusting apparatus has tops and bottoms respectively aligning with tops and bottoms of the left frame and the right frame when the at least one adjusting apparatus is assembled to the swimming goggles. 
   
   
     3. The swimming goggles as claimed in  claim 1 , wherein the arcuate spring comprises two short sides connecting with the engaging block, and a long side transversely connecting with ends of the short sides and being arcuate for providing resiliency. 
   
   
     4. The swimming goggles as claimed in  claim 1 , wherein the first engaging portion includes L-shaped jags respectively in upward and downward edges of the engaging block, and wherein the embedding portion includes a pair of L-shaped projections for latching the L-shaped jags. 
   
   
     5. The swimming goggles as claimed in  claim 1 , wherein the second engaging portion includes positioning grooves respectively adjacent to the left frame and the right frame for cooperating with the barbs of the cover. 
   
   
     6. The swimming goggles as claimed in  claim 4 , wherein an engaging hole is defined in the engaging block, and wherein the base forms a reinforce post between the L-shaped projections for cooperating with the engaging hole. 
   
   
     7. The swimming goggles as claimed in  claim 1 , wherein the base further defines locking holes in opposite sides thereof, and wherein the cover further forms locking posts at sides thereof for cooperating with the locking holes. 
   
   
     8. The swimming goggles as claimed in  claim 1 , wherein the button has an inclined surface for facilitating manual operation. 
   
   
     9. The swimming goggles as claimed in  claim 1 , wherein the distance between the fixing axis and the tip of the inclined surface of the button and is larger than the distance between the fixing axis and an extreme end of the biasing arm. 
   
   
     10. The swimming goggles as claimed in  claim 1 , wherein the connecting apparatus is a nose support, and the nose support is integrated with the left frame and the right frame. 
   
   
     11. The swimming goggles as claimed in  claim 1 , wherein pads are integrally formed on the inner surfaces of the left frame and the right frame, and wherein the left frame, the right frame, the connecting apparatus and the pads are integrally formed of soft material.
